Isolated Metachronic Metastatic Clear Cell Renal Cell Carcinoma in the Thyroid gland 7 Years After Nephrectomy

摘要

Thyroid gland is a rare site for distant metastases. The aim of this study is to present a rare case of an isolated metastatic clear cell renal cell cancer (ccRCC) in the thyroid gland seven years after left-sided nephrectomy.A neck cancer discovered by clinical examination, diagnosed by ultrasound-guided USG fine-needle biopsy was removed by surgery. Palliative thyroidectomy with consecutive neck radiotherapy was finished without any complications, except a temporary, asymptomatic hypocalcaemia. After six month remission, the patient’s general condition deteriorated, multiorgan RCC dissection appeared leading to the patient’s death.
